bbbbd9002f
This patch adds the stm32f2xx System Configuration Controller. This is used to configure what memory is mapped at address 0 (although that is not supported) as well as configure how the EXTI interrupts work (also not supported at the moment). This device is not required for basic examples, but more complex systems will require it (as well as the EXTI device) Signed-off-by: Alistair Francis <alistair@alistair23.me> Reviewed-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Message-id: 5d499d7b60b61d5d6dcb310b2e55411b1f53794e.1424175342.git.alistair@alistair23.me Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
